Adhesive labels and manufacture thereof

ABSTRACT

Adhesive labels are manufactured by cutting windows in an upper layer of a support web ( 2 ) through to a lower silicon coated material. Folded leaflets ( 15 ) are then adhered by lines of adhesive ( 11, 12, 13 ) to the support web ( 2 ) and the combination is die-cut to form individual adhesive labels with part of the die-cut folded leaflet extending beyond an edge of a base label formed from the window in the support web. This method of manufacture permits more complex label structures to be constructed without pre-cutting individual base labels.

BACKGROUND OF THE INVENTION

The present invention relates to adhesive labels and to the manufacturethereof In particular, the present invention is concerned with a methodof manufacture of adhesive labels that affords greater flexibility inthe construction of the adhesive labels and improvements in the economyof production. Moreover, the present invention is further concerned withadhesive labels manufactured by such a method that are particularlysuited for use on cylindrical and other non-planar surfaces.

Numerous variations of self-adhesive label designs have been developedfor the packaging industry to enable additional information to beprovided with a host product or its packaging. In general, such labelsare provided on a reel of silicone-lined release material to permitautomated transfer of the self-adhesive labels from the release materialto the host product or packaging

One example of the many different designs of self-adhesive labelsavailable may be found in EP 0628941. Reference is made in particular toFIG. 13 of EP 0628941 which shows a web of release material to which aweb of supporting labels is adhered by a layer of adhesive. The web ofsupporting labels is initially cut and the waste removed to define aseries of individual labels, spaced apart from one another, each ofwhich is larger than its desired final size. A layer of adhesive is thenapplied over the top surface of each of the support labels and beyondone edge of the support label to overlie the release material.Individual folded leaflets are adhered by the continuous layer ofadhesive to respective support labels so that the top panel of thefolded leaflet extends beyond the one edge of the support label toadhere to the adhesive overlying the release material. Finally, a layerof transparent laminar material is applied over the support label andthe folded leaflet and the layered structure is cut to the desired shapewith the waste being removed.

The method of manufacture of the self-adhesive label design describedabove presents a number of disadvantages to the commercial production ofself-adhesive labels of this type. For example, the fact that a layer ofadhesive is used results in the entire free edge region of the top paneloverlying the release material being permanently adhered to the hostproduct making the label difficult to open and increasing its stiffnessmaking the label inappropriate for use on highly curved surfaces.Furthermore, the entire lower surface of the folded leaflet is securedto the support label thereby preventing the lower surface of the bottompanel and that part of the upper surface of the support label beneaththe bottom panel being used to present additional printed information.It should be noted that the method of manufacture described aboverequires the support labels to be individually formed before the foldedleaflets are applied. This limits the manufacturing method to singleleaflet application to support labels, increases the complexity of theinitial manufacturing steps, and increases the need for accuratealignment between the support labels and the folded leaflets.

SUMMARY OF THE INVENTION

The present invention seeks to overcome at least some of thedisadvantages described above and seeks to provide a novel method ofmanufacturing adhesive labels and to an improved adhesive labelmanufactured by such a method.

The present invention provides a method of manufacturing adhesive labelsconsisting of a base label and a multi-page leaflet secured thereto, themethod comprising the steps of: providing a support web on a web ofrelease material, the support web having a plurality of windows exposingportions of the web of release material therethrough; securing aplurality of multi-page leaflets to a top surface of the support websuch that an end region of each multi-page leaflet overlies one or morewindows: and cutting the multi-page leaflets and the support web todefine a plurality of adhesive labels each having a portion of themulti-page leaflet adjacent the web of release material.

Preferably, the-multi-page leaflets are secured to the support web byone or more regions of adhesive. Ideally, one or more lines of permanentadhesive are used to secure the multi-page leaflet to the support web.

In a preferred embodiment adhesive is applied to regions of the releasematerial exposed through the windows in the support web so that saidportion of the multi-page leaflet is adhered directly to the web ofrelease material. The end region of the multi-page leaflet may includean unadhered tab portion extending beyond the portion of the multi-pageleaflet adhered to the web of release material.

Whilst any one of many different methods may be employed to remove thecut patches the preferred method is one in which the cut patches of thesupport web are removed by supplying the web of release material and theweb of label material to a projecting edge, with the web of labelmaterial facing away from the surface of the projecting edge, andpassing the support web over the projecting edge thereby causing the cutpatches to fall away from the web of release material. Ideally, the webof release material and the web of label material are fed to theprojecting edge in a direction that ensures the adhesive surface of theremoved patches face generally upwards.

The method may further include providing a covering layer of a laminatematerial over at least a part of the support web and the multi-pageleaflets. Ideally, the covering laminate material is applied to thesupport web and the multi-page leaflets prior to the cutting of themulti-page leaflets and the support web into individual adhesive labels.

In a further aspect the present invention provides a method ofmanufacturing an adhesive label assembly which comprises the steps of:providing a continuous web of adhesive label material on a-web ofrelease material; cutting a plurality of windows in the web of labelmaterial as far as the web of release material; and disposing of the cutpatches of the web of label material.

The present invention also provides an adhesive leaflet manufactured inaccordance with the method described above and an adhesive labelassembly manufacture in accordance with the method described above.

The present invention further provides an adhesive leaflet assemblycomprising a web of release material, a plurality of base labels formedfrom a support web and releasably adhered to the web of releasematerial, a multi-page leaflet disposed on each one of the plurality ofbase labels such that an end region of each multi-page leaflet extendsbeyond an edge of the respective base label to overlie a window exposinga portion of the release material.

Preferably, the exposed upper surface of the base label and the uppersurface of the multi-page leaflet are uncovered and do not include atransparent laminar material.

DETAILED DESCRIPTION OF THE INVENTION

The method of manufacturing adhesive labels diagrammatically representedin FIG. 2 starts with a base or support web 2 stored on a reel 3. Thesupport web 2 comprises a silicone coated release material having alayer of adhesive thereon and a top support layer with the top supportlayer facing outwardly on the reel 3. The support web 2 is initiallyprinted at a printing station 1 with the desired image along with anyindex and leaflet registration markings The images and the index andregistration markings are repeated along the longitudinal length of thesupport web 2, the longitudinal direction being parallel to thedirection of motion of the support web during the manufacturing process.Also, there may be multiple images printed across the transverse widthof the support web. Although it is convenient to print the registrationmarkings on the support web, as an alternative the indexing andregistration markings may be stamped or cut into the support web,preferably adjacent one or both edges of the support web.

From the printing station 1, the support web 2 is supplied to adie-cutting station 4 at which windows 5 are cut through the uppersupport layer but not through the release material leaving patches 6unconnected to the remainder of the upper support layer. In FIG. 3 thewindows are shown as being generally rectangular. However, alternativeshapes may be cut out from the upper support layer as required includingshapes having curved or irregular edges. The locations of the windowsare determined using the indexing marks printed on the upper supportlayer and are aligned with any existing printed images on the uppersupport layer The patches 6 are removed from the support web 2 to formthe windows 5, for example employing a dispensing beak 7, more clearlyshown in FIG. 3, where the patches 6 are received in a waste bin 8.

The dispensing beak 7 is generally triangular in cross-section,preferably a right-angled triangle, with the most acute angle of thetriangle being the edge over which the support web travels. It will, ofcourse, be appreciated that alternative arrangements of the dispensingbeak 7 may be used to remove the patches 6 from the windows 5.

The support web 2 with the windows 5 may be manufactured separately andsupplied to the machinery on a reel as an adhesive label assembly or, asshown in FIG. 2, the formation of the windows may be part of acontinuous in-line manufacturing process. As can be seen from FIGS. 2and 3, where formation of the windows 5 is part of a continuous labelmanufacturing process, the support web 2 is fed to the printing station1 and the die-cutting station 4 with the upper support layer facingdownwardly (as seen in FIG. 2) This ensures that when the upper supportlayer 2 is fed to the dispensing beak 7, the upper support layer facesoutwardly from the dispensing beak 7. This ensures that the patches 6can be easily removed and the upper support layer is uppermost in thesubsequent manufacturing steps. Moreover, the support web 2 ispreferably fed initially to the lower leading surface of the projectingedge of the dispensing beak 7 and then over the edge of the beak to itsupper supporting surface so that the patches 6 fall with their adhesivesurface uppermost. It is envisaged that the patches 6 could be collectedand reused in other label products.

Conventionally the dispensing beak 7 is used to remove self-adhesivelabels from release material when the self-adhesive labels are beingapplied to a host product or packaging. This requires the self-adhesivelabels to be removed from the release web with the adhesive side of thelabels directed downwardly. To do so, the web of release materialbearing the individual self-adhesive labels is supplied to the uppersurface of the dispensing beak and is then passed over the point of thedispensing beak and around to the lower surface of the beak. However,with the manufacturing method shown in FIG. 3, as the patches 6 are awaste by-product in this process, rather than the final label product,the normal operation of the dispensing beak 7 is undesirable. Hence, thesupport web 2 is preferably supplied to the dispensing beak 7 in theopposite direction, i.e. initially to the lower surface of thedispensing beak, to ensure that the patches fall into the waste bin 8with the adhesive uppermost and the upper support layer is uppermost inthe subsequent manufacturing steps.

Instead of individual windows being manufactured by this method acontinuous transverse strip may be die-cut from the upper support layerat regular intervals along the longitudinal length of the support weband removed using the dispensing beak 7. Where a continuous strip isremoved from the support web 2, the edges of the strip may include arepeating pattern of curves or steps depending upon the desired finalshape of the adhesive label. One of the edges of the window will,ultimately, form an edge of a base label cut from the support web.Whether individual windows or a continuous transverse strip is cut fromthe support web 2, at least in the transverse direction, the support webremains a sheet overlying the release material and is not divided intoindividual base labels.

Once the windows 5 have been formed, lines of adhesive are applied tothe upper support layer and to the exposed release material in thewindows. Three adhesive dispensers 9 a, 9 b and 9 c are shown in FIG. 2,the first and third dispensers 9 a and 9 c apply permanent adhesivewhereas the second dispenser 9 b applies releasable adhesive. Thedispensers 9 a, 9 b and 9 c may be operated simultaneously orsequentially, as desired. In FIG. 4 the location of the lines ofadhesive are shown and consist of: a first line of permanent adhesive 11extending across the support web 2 in a transverse direction adjacentthe windows 5 applied by the first dispenser 9 a; a second transverseline of permanent adhesive 12 on the support web 2, parallel to thefirst line of permanent adhesive 11, located distant from the windows 5,applied by the third dispenser 9 c; and a third line of resealableadhesive 13 on the release material, parallel to the first line ofpermanent adhesive, located within each of the windows 5 applied by thesecond dispenser 9 b. The alignment of the lines of adhesive is ensuredusing conventional indexing techniques and the adhesives are appliedusing conventional techniques, for example-hot or cold nozzleapplication in either intermittent or continuous motions. Alternatively,lines of adhesive can be printed onto the support web 2 and the releasematerial,

Ideally, the same adhesive is applied by all three dispensers 9 a, 9 band 9 c for example Danikumlin 5818 and the material in contact with theadhesive determines whether the adhesive forms a permanent, orreleasable contact. Alternatively, different adhesives may be applied bythe individual dispensers, for example Addex 100 in dispensers 9 a and 9c and Danikumlin 5213 in dispenser 9 b.

Once the lines of adhesive 11, 12, 13 have been applied to the supportweb 2 the support web is fed to a leaflet dispensing station 14. At theleaflet dispensing station 14, multi-page leaflets such as foldedleaflets or booklets 15 are applied to the upper surface of the supportweb over the lines of adhesive 11, 12, 13. The positioning of the foldedleaflets 15 over the lines of adhesive is performed using conventionalregistration techniques and any registration markings printed on theupper surface of the support web 2. Preferably, the folded leaflets 15are applied with their folded edge or spine facing towards the directionof travel of the support web. The direction of travel of the support webis indicated by an arrow in FIGS. 4 to 6.

Where more than one window or a continuous strip has been die-cut in atransverse direction across the support web with the intention ofmanufacturing two or more adhesive labels across the width of thesupport web, as shown in FIGS. 4, 5 and 6, the folded leaflet 15 appliedto the support web 2 preferably extends across all of the windows 5 andthe support web in a transverse line. In this case the folded leaflet 15is printed with multiple identical images according to the number ofwindows extending across the transverse width of the support web 2.Alternatively, the folded leaflet may be printed with different imagesfor different transverse regions of the support web 2 or a plurality ofseparate folded leaflets with different printed images may be appliedacross the transverse width of the support web 2.

Each folded leaflet 15 consists of a bottom panel connected to a toppanel along a folded edge 18. Inner panels or pages may additionally beprovided between the top and bottom panels and are preferably connectedto the bottom panel along a further folded edge located beneath the toppanel. The inner pages may be folded in either a zig-zag or circulararrangement. Alternatively the inner pages may be secured between thetop and bottom panels by means of a suitable adhesive or by means of astapled construction. In all cases, however, a free end region 19 of theleaflet extends beyond the edge of the windows 5. Preferably, the freeend region 19 is an extension of the top panel that extends beyond theedge of the bottom panel 20 and the edges of any inner pages, distantfrom the folded edge 18.

The folded leaflet 15 is aligned with the lines of adhesive such thatthe free end region 19 overlies the windows 5 with the resealable linesof adhesive 13 and the first line of permanent adhesive 11. The foldededge 18 of the leaflet is positioned beyond but close to the second lineof permanent adhesive 12. In this way the folded leaflet 15 is heldsecurely to the support web 2 at both transverse ends during themanufacturing process. In this position the edge of the bottom panel 20,distant from the folded edge 18, and the edges of any inner pages arepositioned between the second line of permanent adhesive 12 and thewindows 5. Preferably, the edge of the bottom panel 20 is close to theedge of the windows 5.

The support web 2 bearing the folded leaflets 15 then travels to adie-cutting station 21. At the die-cutting station either simultaneouslyor consecutively the support web and the folded leaflets are cut usingflat-bed or rotary cutting apparatus to the desired size and shape.During this cutting operation as shown in FIG. 6, the upper supportlayer and underlying layer of adhesive of the support web 2 is cut inone region down to but not through the release material. In a secondregion the folded leaflet 15, the second line of adhesive 12, the uppersupport layer and the underlying layer of adhesive are cut through asfar as but not through the release material. In a third region the freeend region 19 of the top panel only is cut, over the window 5. In FIG. 6the thinner line indicates where the first region is cut, the thickerline indicates where the second region is cut and the dashed lineindicates where the third region is cut.

With this method of manufacture the folded leaflet 15, the support web 2and the free end region 19 of the top panel may be cut to any desiredshape be it rectangular or generally circular, for example.

Moreover, the free end region 19 of the top panel may be shaped todefine a tab 22, unadhered to the underlying release material, beyondthe line of resealable adhesive 13. The tab 22 is an aid to the openingand closing of the folded leaflet when the adhesive label is applied toa host product or packaging.

As can be seen from FIG. 6 it is at this stage that the folded leaflet15 is divided into individual folded leaflets, one for each windowacross the transverse width of the support web It should be borne inmind that until this final die-cutting step the upper support layer ofthe support web 2 has not been divided into individual base labels.Instead, up to this die-cutting operation the upper support layerremains a sheet overlying the release material having a plurality ofindividual windows or continuous transverse strips cut out therefrom.

Once the die-cutting is completed the waste material 23 is removed andthe release material bearing individual adhesive labels is stored on areel 24. It will be apparent that the waste material 23 includes theentirety of the first line of permanent adhesive 11. Before beingcollected on a reel, where two or more individual adhesive labels arearranged across the transverse width of the release material, therelease material may be slit between the adhesive labels to form singlewidth reels of base labels and folded leaflets.

FIG. 1 shows an adhesive label manufactured according to the methoddescribed above on a web of silicone coated release material 25. Theadhesive label consists of a base label 2 onto which a folded leaflet 15is adhered. The folded edge 18 of the leaflet is preferably locatedinboard of the edge of the base label. Alternatively, if desired, thefolded edge 45 may be coincident or immediately adjacent with an edge ofthe base label. The longitudinally extending edges of the folded leafletand the base label are coincident in FIG. 1 but this need not be thecase where it is desired to have a slightly larger base label, forexample. In this case separate die cutting of the folded leaflet and thebase label would be required. The free end region 19 of the top paneloverlies the line of resealable adhesive 13 which holds only a portionof the free end region in a closed state against the release materialBeyond the line of resealable adhesive 13 the free end region 19terminates in a tab 22 that is unadhered to the release material.

Tear lines, that may include perforations, may be provided in one ormore of the panels of the folded leaflet.

Although the adhesive label described above includes a tab formed fromthe edge of the top panel of the folded leaflet, such a tab is notessential to the construction of the adhesive label. The free edge ofthe top panel may be cut to any desired shape whilst ensuring that atleast a part of the free edge region of the top panel overlies theresealable adhesive. For example, the free edge of the top panel may lieparallel to the folded edge of the leaflet, a notch may be cut into thefree edge of the top panel to provide easy access when lifting the freeedge of the top panel or a similar tab or notch may be formed on alongitudinal edge of the top panel extending between the folded edge andthe free edge.

Whilst the adhesive label described above consists of only a supportlabel and a folded leaflet, it is envisaged that a plastics laminarmaterial may be applied over part or all of the folded leaflet and/orthe exposed portions of the support web and that the laminar materialmay be transparent and/or may be suitable for over-printing. Preferably,the plastics laminar material is applied after the folded leaflets havebeen adhered to the support web but before the die-cutting station 21.The laminar material is preferably self-adhesive and so adheres to theexposed upper surfaces of the support web 2, the folded leaflet 15 andthe release material through the windows 5. The edges of the laminarmaterial may be contiguous with the edges of the base label and thefolded leaflet after die-cutting with the folded leaflet 15 held closedby the adherence of the free edge region 19 of the folded leaflet to therelease material. Alternatively, the folded leaflet may be pre-cut asshown in FIG. 7 so that only a portion of the transverse width of eachadhesive label projects across the window 5 to adhere to the line ofadhesive 11. In this arrangement the line of resealable adhesive 13 maybe omitted. Instead, the self-adhesive laminar material that overliesthe base label and the folded leaflet adheres to the release material(identified by 23 in FIG. 7) and ensures the folded leaflet is heldclosed without the need for the free edge region 19 to have adhesive onits inward facing surface. With this arrangement again an unadhered tabor flap is provided to assist in the opening of the folded leaflet. InFIG. 7 the dashed line indicates the periphery of the die-cut adhesivelabels.

Although in the above description it is the free edge regions of thefolded leaflets 15 that overlie the windows 5, in an alternativearrangement it is envisaged that the folded edge or spine of the leafletoverlies the windows 5 and part of that portion of the leaflet thatoverlies the windows may be releasably adhered to the release material.With this arrangement the leaflet is folded so that it may be openedfrom underneath. For example, the bottom panel of the leaflet may beshorter than the top panel so that when the leaflet is secured to thesupport web the line of adhesive 12 adheres to the inner surface of thetop panel leaving the lower panel unadhered to the support web. Thus,when opening the leaflet, the folded edge or spine of the leaflet islifted away from the base label and the bottom panel is unfoldedoutwards.

With the method of manufacture described above the support web is notcut into individual base labels until the final die-cutting operationwhere all of the shaping of the adhesive label is performed together.This enables more complicated shapes to be produced that would bedifficult if not impossible to produce where alignment between apre-die-cut base label and a subsequent die cutting operation would benecessary. Furthermore, because only lines of adhesive are employed, therear surface of the bottom panel and the upper surface of the base labelmay be used to present additional pre-printed information. Thisincreases the total number of sheets available in the adhesive label.The use of lines of adhesive also ensures that the free edge region ofthe top panel may be easily grasped and the folded leaflet therebyopened by means of a tab or other unadhered portion.
